Help Needed !

I dont mean this to sound confrontational in any way but reading what you have in your tank you list 30 fish in a 180l. ( i`m only assuming the 180 holds 180l i dont actually know ) also do you think re homing any fish would save the fighter

actually, its 26 , 2 of those are in a hospital tank too, and one is being rehomed shortly. all the others dont grow any bigger than 2.5-3", unlike yours
your poor betta could be getting beaten up by any of your fish. you defo need to get him a new tank! im sure you'll do the best you can for him, especially now you're getting advice here

Yes new betta tank as soon as shop opens tomorrow hopefully he`ll still be around to go in it.
It seems a common opinion that some of my fish are going to get too big for my tank, but which ones ? as when I bought them (except for the angels which I knew would get big but was nieve when I got them ) I was told they would be ok.
Which fish are going to get too big

hmm... from what i know i don't think anythings going to out grow it except it is overstocked gouramis should be fine and rainbow fish i don't know anything about them

I have a 125l tank, well planted, with red tail black shark, 2 cory sterbai, 2 rasbora scissor tails,5 neons, 5 forktail rainbows, 2 honey gouramis, 3 angels and a clown plec but as I said the last fish added was the plec about 3 weeks ago and they all get allong fine.

Which fish would you say are not suitable for my tank ? Whenever I buy a fish I alway ask what the expected adult size is and the only fish I thought might get too big would be the scissor tails ( told about 6" ) and the angels, whitch I regret buying as they`ve been nothing but trouble.
Which fish are known for atacking bettas ( your going to say the angels arn`t you ! )
and I dont mean to appear thick but by water parameters do you mean test results or dimensions of tank ?
No2=0 No3=10 PH=7.5 CL2=0 tank size 800mm x 400mm x 500mm

Potentially problematic:
* the red tailed sharks (Epalzeorhynchus bicolor) can get quite aggressive
* Gouramis do not get along with Bettas, although probably not a problem in your tank if it is well planted
* the tank is too small for Angels, also they are serial offenders when it comes to Betta harassment
* Scissor-tail Rasboras (Rasbora trilineata) get too big for your tank, are schooling (keep 6+) and are potential nippers (if only because you do not have a school of them)

..and I should probably mention the following:
* corys are schooling fish, it is better to keep 6+
* if there is any conflict between Gourami and Bettas, then another female should considerably help
* the pleco could potentially have a go at the Betta if the others harass the Betta so much that it needs to rest on the bottom (probably not happening, nor a problem, but keep in mind)

small betta tank it is then. I cant just watch him die. The pain is ive got 3 tanks but the second ones got another fighter in it and the others got fry in it, I know which one he`d rather go in but im not sacrificing all my fry to him. Would you say if I used tank water to fill it and some media from my other filter he could go straight in or would it need a small cycle?

Aye, the best solution What you suggest works for me without a problem. Of course, be careful, test water every day, etc, etc.. and of course, good luck! Do ask on here and/or other places online before buying new fish! Most LFS are after a profit.
