[quote=tbtregenza;2506393]Thanks for reply - I have had him for about 2.5 weeks now. I have changed his water once to twice a week. He has no heater right now but I just bought a small one for tanks up to 1.5 gallons on Amazon. I read they like temp between 77 and 80, and he IS living in currently low to mid 70's water.
Do you think that could be the issue? Temp is part of the issue, so great that you're addressing that. Keep a close eye on whichever heater you purchased. The pre-set heaters sometimes don't work as they should so just keep an eye on the temp.
I bought a small silk plant for him and a turkey baster to remove impurities between water changes. He is probably no more than 1.5 inches long right now. I have used the water conditioner whenever putting in new water. I also have been putting in that "Betta Revive" stuff to try to get him healthy again. About 5 drops when I feed him.
A few silk plants & a cave will be great, they don't like being so exposed. I've never used Betta Revive so I can't comment on it effectiveness.
I use Brita-filtered tap water that I allow to get to room temp before putting in (by leaving in an bowl overnight next to him).
I would use regular tap water but I'm not sure it would make too much difference since your water isn't going through an elaborate filtering system
I also just bought him one of those little stick-on betta "leaf" hammocks.
Most Bettas love those, as someone else stated you'll want to remove the wire if there is one as it can rust & cause problems.
He (I think?) was a house warming gift so he took us by surprise a little - have been playing "catch-up" on his accommodations.
You're not alone, most of us didn't know what we were doing when we purchased our first Betts.
EDIT: I also have been feeding him those frozen brine shrimp (after thawing). He is not taking well to those betta "Bio Gold" pellets (he spits them out!)
I would recommend New Life Spectrum (NLS) or Omega One pellets, Brine Shrimp is good but I don't think its meant to be their main diet. NLS are smaller than Omega One & most Bettas will not say no to them.[/
..... Oh, in a bowl that size you'll want to do at a minimum 2 water changes per week & I wouldn't worry about a filter it.
