With small fish tanks, you must do fifty percent or larger water changes at least twice weekly but preferably every other day. Without massive, frequent water changes, the tank can destabilize and put your fish at risk. Thus, it is important to schedule time to do your fish tank water changes and cleaning. Every other week, perform deep cleanings in which you remove decorations and scrub the interior.  Observe your fish daily to see whether they look healthy and are behaving normally. Do they have good color, clean scales, unclamped fins? Or are they slimy and ragged? Remove any dead fish. If your fish look sluggish, stressed, or they are gulping for air, do a water change.  It is not beneficial to perform deep cleanings too often, as you will remove essential bacteria. Make a checklist to ensure that you have all the necessary supplies. Having your supplies on hand will speed up the process. Most supplies are available at pet or home goods stores. Use this list to help you.  2 fish nets Temporary fish tank or container Fresh water in the quantity you want to replace Algae pad New toothbrush 2 large buckets (5-10 gallons) Gravel vacuum Siphon Water conditioner Aquarium-safe glass cleaner or a vinegar-based solution Clean cloth Towel Place tarps or towels on the floor to catch any spilled water. Keep the tank in place. Do not move your tank or tip it into the sink. Juggling your fish puts them under stress and stirs debris in the tank. Wear a short-sleeved shirt or tank top. You might consider wearing a bathing suit. Aprons also can protect your clothing. Wearing water-resistant shoes like water shoes or flip flops is also a good idea. If applicable, unplug the aquarium’s aerator, filter, and heater. Leave hood lights plugged in. Place the hood behind the tank to illuminate the tank.

In fact, forget the term all together. If you are interested in dating and/or having a romantic encounter with an older woman, you’ll need to treat her like a human being — not some sexist stereotype of how a sexually active older woman looks and behaves. The generally accepted age group for cougars is 40-plus; however, some people go as low as 35 in their definition. With new creams and procedures available, many men and women are able to look much younger than they are. Some things you can look for, which apply to both sexes:  Dry, dull and/or thinning hair: both men and women experience a decrease in the quality of their hair as they get older. You might notice that an older woman has brittle-looking hair that lacks the shine and fullness of younger people. Her hair might also be dyed to cover grey hairs.  Sparse eyebrows and eyelashes: as we age, our hormones drop and hair growth slows, which can make our eyebrows and eyelashes less lush. Some women might opt for pencilled or tattooed eyebrows, and eyelash extensions — so it still might be difficult to judge their age based on these factors alone. Thinner lips and eroded tooth enamel: our lips wrinkle and thin with age, and our teeth wear down and erode. You might notice thin lines around an older woman’s mouth, thinner lips (maybe partly hidden with lipliner), and duller or translucent teeth. Thin skin: as men and women get older, the smooth skin on their necks gain ridges and wrinkles — unless they use Botox or have a face-lifts, that is. Thin skin will also be apparent on the hands, making veins, knuckles, and tendons more visible. Dry and saggy knees and elbows: with age the skin around our knees and elbows begins to dry and sag around the joints. The skin around the elbows in particular can become darker and much drier than the surrounding skin. Evolutionary psychology has shown that when evaluating women’s desirability, physical attractiveness is a more important factor than it is in evaluating men’s desirability. This means that while less attractive men might still be desirable based on their intelligence, humor, income, etc., women are still largely judged on how they look. For this reason, it makes sense that with age, a woman might amp up her makeup routine to try to hide the signs of aging that will make her less desirable.  You might notice an older woman wearing more foundation and structuring creams and shades to help give her face a smooth, contoured look. She might also be more likely to wear lipliner to make her lips look fuller, a brow pencil to fill in her eyebrows, and blush to make her cheeks look more youthful and rosy.   Contouring is a popular makeup technique right now, used by women in all age groups, from their teens upward. The comical cougar stereotype is of a woman wearing clothes that are much too young, and often too tight, for her — usually in tacky fabrics such as animal print. The reality is that women of any age can dress in a tasteless and unflattering manner.  How a woman dresses — regardless of her age — depends largely upon her own personal sense of style. While women of all ages wear push-up bras, older women may find them even more useful as their breasts will sag with age. In general, the older a woman gets, the better she knows herself and what she likes, and the more confident she becomes. Some signs that she is confident:    Good posture: whether sitting or standing, a person with good self-confidence will likely have a straight back and a head that is well-balanced on the neck, with the chin pointed neither too high nor too low. Relaxed: a person with good self-confidence will likely seem relaxed in most situations, perhaps looking around the room with an easy smile, or just seeming generally calm and at peace with herself. She won’t be very fidgety. Eye contact: confident people make eye contact and maintain it in social interactions. That said, there's a difference between maintaining eye contact and staring intimidatingly at someone: looking someone in the eye roughly 60% of the time you are talking to them is a good rule of thumb.

If your email is formal, sign off with something like “Best regards,” or (for an even more formal touch) “Sincerely.” For less formal emails, you may be fine using something like “Take care” or “Cheers.” If you’ve had previous emails from the person you’re writing to, you might look at their sign-off and match your tone to theirs. For example, if they tend to sign with something like “Warm regards,” you should sign off with a similar level of formality. Like the closing sentence, a sign-off can also reflect the purpose of your email. For example, if you’re making a simple request or briefly expressing gratitude for something, you might use a sign-off like “Many thanks,” or “Thanks so much,” followed by your signature. Unless you know the person you’re writing to very well, avoid anything too slangy, informal, or affectionate. In general, things like “Love,” “XOXO,” or “Hugs” should not be used in business emails. If your email is part of a long chain, or if you’re trying to communicate something very briefly and quickly to a co-worker, it may not be necessary to include a sign-off at all. If you don’t feel comfortable skipping the sign-off altogether, a simple sign-off like  –Bernice or –B. should be just fine for brief, informal emails.
